Definitions

  • the present invention relates to a method for coating a powder compact, in particular for producing a capsule containing beverage powder which is suitable for preparing a beverage such as cocoa, tea or coffee.
  • coffee capsules in addition to coffee pods, have been increasingly used in recent years, the capsule walls of which are usually made of stainless steel, aluminum or plastic.
  • Such capsules allow coffee powder to be stored for a longer period of time without loss of flavor.
  • such capsules allow a quick and user-friendly production of a coffee portion with the desired flavor by inserting a capsule with the desired type of coffee into a coffee machine adapted to it, in which hot water is then pressed through the capsule and coffee brewed from it is made.
  • such capsules are comparatively expensive, inter alia because of the capsule material used and the production-intensive capsule construction.
  • Such capsules are also problematic from an environmental point of view.
  • the capsules are not recyclable and are usually disposed of as residual waste by the consumer after use. There is therefore practically no recycling of coffee capsules, which is particularly problematic in the case of aluminum-based coffee capsules, since the production of aluminum is very energy-intensive, which results in a particularly poor CO 2 balance in such capsules.
  • Another major disadvantage is that such capsules are not biodegradable and therefore cannot be disposed of biologically. In view of the fact that in Germany alone well over 2 billion coffee capsules are used every year, this is a serious problem.
  • capsules made from alternative materials have already been proposed.
  • capsules which are filled with coffee or tea in their interior and comprise a capsule wall which, in addition to the capsule content, also contains water as a structuring component.
  • a capsule wall which, in addition to the capsule content, also contains water as a structuring component.
  • the capsule is cooled to below the freezing point of the structuring component, because the structuring component melts when its freezing point is exceeded and moisten the capsule contents. Naturally, this limits the use of such capsules considerably.
  • WO 2009/053811 A2 describes a capsule that can contain ground coffee, cappuccino powder, chocolate powder, milk powder or tea powder.
  • the capsule comprises two half-shells which form the capsule walls.
  • the capsule walls are made of a water-soluble material that dissolves during the brewing process. With this concept, the capsule wall material is dissolved during the brewing process and thus part of the prepared drink, which can have an undesirable effect on the taste. Apart from that, the production of such capsules is complex and expensive.
  • the capsule which is particularly suitable for the production of coffee and which comprises a pellet made from a powder containing at least one polysaccharide, such as coffee powder, the pellet being encased with at least one coating layer, the at least a coating layer comprises a crosslinked polysaccharide.
  • the coating layer is composed of an alginate and is obtained by immersing the compact in an alkali metal alginate solution before the compact thus treated is immersed in an alkaline earth metal salt solution.
  • the alkaline earth metal ions act as crosslinkers, since they form coordinative or ionic bonds with groups of the alginate.
  • a water-insoluble coating is obtained which does not impair the taste of the beverage produced from the capsule and provides sufficient stability of the capsule to ensure protection during transport and handling without the capsule contents suffering any appreciable loss of flavor.
  • the coating material does not adhere well to the hydrophobic coffee powder compact. This makes it difficult to transfer and immerse the powder compact from the alkali metal alginate solution into the alkaline earth metal salt solution. Even if this is done carefully and with the help of specially designed receptacles and holders, obtaining a sufficiently uniform coating thickness on the powder compact is difficult, if at all possible.
  • the present invention is based on the object of providing a method for coating a powder compact, in particular for producing a capsule containing beverage powder for the portion-wise preparation of beverages from beverage powder, such as cocoa, tea and coffee, with which a coated powder compact is simply and reliably is obtained with a uniform coating thickness.
  • This solution is based on the knowledge that by using a container with a container wall made of a perforated material which encloses a cavity, the container having an inlet opening for introducing coating liquid, a powder compact can be coated easily and reliably, with a uniform thickness the coating of the powder compact is obtained. Since the powder compact introduced into the cavity of the container in step iii) has a smaller volume than the cavity, and therefore the powder compact fits into the cavity, a gap is formed between the powder compact and the inside of the container wall made of perforated material that delimits the cavity of the container which can be filled with the coating liquid in step iv) by introducing the coating liquid.
  • the air initially present in the interspace is displaced by the coating liquid, so that in step iv) the entire interspace can be completely filled with the coating liquid.
  • the powder compact floats on the introduced coating liquid, the powder compact is surrounded by a uniformly thick layer of coating liquid when the gap is completely filled with the coating liquid.
  • the hardening liquid has a lower viscosity than the coating liquid, the hardening liquid can enter the container quickly and evenly over the surface of the container through the perforated material, i.e.
  • step v) via its small holes, during step v) and thus contact the coating liquid, whereas the Due to its higher viscosity, the coating liquid does not escape from the container through the perforated material.
  • a coated powder compact with a uniform coating thickness is thus obtained simply and reliably by the method.
  • perforated material is understood to mean a material that has a multiplicity of small holes, the holes being regularly arranged in the material and each having at least substantially the same shape and size.
  • the present invention is not particularly limited. Good results are obtained in particular when the powder compact contains or is preferably composed or consists of a material which is selected from the group which consists of coffee, tea, drinking chocolate, cocoa and milk powder. Good results are obtained in particular when the powder compact consists of ground coffee powder.
  • a powder compact is understood to mean compacted powder.

  • This provides sufficient compression so that the powder compact can be safely encased and a good oxygen barrier is achieved.
  • the powder compact can have any shape.
  • the powder compact is preferably designed spherically. Good results are obtained in particular when the diameter of the spherical powder compact is 1 to 10 cm, preferably 1 to 5 cm, particularly preferably 2 to 4 cm and most preferably 2.7 to 3.7 cm.

  • the porous material preferably the wire mesh, preferably has holes with such a size or such a mesh size that the more viscous coating liquid does not exit through the perforated material, preferably the wire mesh, from the cavity of the container and thus from the container, but the less viscous hardening liquid enters the container quickly and evenly over the surface of the container through the perforated material, preferably the wire mesh, when the container is immersed in the hardening liquid.
